HAY-PRESS.

Speccaton of Letters Patent.

Patented Feb. 24, 1920.

Application filed February l1, 1919. Serial No. 276,338.

To all whom it may concern.'

Be it known that I, RALPH M. HILTON, a citizen of the United States,residing at Newport News, in the county of Wlarwick and State ofVirginia, have invented new and useful Improvements in Haylgresses, ofwhich the following is a specification.

This invention relates to improvements in hay presses, operated byhorsepower, and the principal object of the invention is to providemeans for operating the plunger in a horizontal plane, while heldagainst any vertical or swinging movement.

Another object of the invention is to provide for a double feedingmovement of the plunger for each complete revolution made by therotatable cross head.

The invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing' my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a side view of the invention.

Fig. 2 is a longitudinal section thereof.

3 is a plan view of part of the apparatus.

Fig. 4 is an end view of the support for the rotatable cross head.

Figs. 5 and 6 are detailed views.

Inthese views, 1 indicates the base of the apparatus. On one end of thisbase is supported the. pressino' chamber t?) and the balinQ chamber 8.The pressing chamber is provided with the usual hopper 4 and saidchamber is strengthened bv the horizontal and cross strips 5. T-hischamber receives the plunger head 6. on the bottom of which are locatedthe rollers 7. This pluno'er `is provided with the extension 8 forclosing the hopper when the plunger is in its forward position. Thechamber 2. is provided with the usual dogs 9 for holding the blocks inproper position after beine pushed forward bv the plunfrer. The ibelinochamber is provided with the usual vieldable top 10. The plunger rod 11is held against lateral or vertical movement bv means of the o'uide 19.supported on the base and consisting of a Ueshaped frame 13 carrying therollers 14.

The stop 15 limits the rearward movement of the plunger.

An upright support 16 is located at the other end of the base, and thissupport consists of the upper and lower beams 17, the end beams 18 andthe connecting bars 19. The upper beam of this head supports therotatable cross head 20, which consists of a cylindrical member 21rotatably secured to the upper beam by means of the bolt 22, andprovided with a flange 23, which receives the circular plate 24 on thebottom of the beam Q5. rllhe bolt 22 passes through this plate 24 andbeam 25, so that all of these parts are rotatably connected with theupper beam 17. The beam 25 has its ends reduced by forming recesses 26in the under faces thereof and rollers 27 are located in these recesses.A crank member 28 is supported on the underside of the upper beam 17 bvthe be( rinos Q9 and this crank member has a depending part 30 whichhasits lower end connected with the bar 31 bv an eve bolt 32. and the.other end of this bar 3l is connected with the free end of the plungerrod 11 bv the perforated strip 33 engaging the forked strip 34 connectedwith the end of the plunrrer rod 11. In this wav the connection betweenthe plunger rod 11 and the bor 3l. mav be adiusted. 'The other end ofthe crank member 28 is provided with a curved upwardlv extendinaf memberwhich is adapted to be struck bv the ends of the beam 25 when the semeis rotated, so as to rock the crank member to reciprocate the plunger.rl`he rollers 97 will overcome friction between the members and preventundue, wenn A sweep 36 is connected with one end ot the beam Q5 and thissweep has the usual tree 37 secured thereto. Brace rods 3S connect theupper end of the support 16 with the base and the spring 39 connects thecrank member with a part of the base. so as to return the crank memberto its normal poeitfm with the plunger rod in its wmmnost position.

It will thus be seen that the plunger is moved forwardly twice on eachrevolution of the beam 95. It, will also be seen that the guide 13prevents anv swinging or lateral movement ot' the plunoer rod so thatthere is no dancer of the plunger becoming jammed in the feedingchamber.

What I claim is:-

1. A hay press comprising a feeding chamber, a plunger therein, aplunger rod connected With the plunger, an upright support, a crankmember rotatably connected with said support and comprising a dependingpart and. an upward extending member, a rod connecting said dependingpart with the plunger rod, a spring connecting the crank member With apart of the press, a rotatable member carried by the support, la beamcarried by said member and having its ends adapted to strike theupwardly eX- tending member of the Crank member, and a sweep connected ywith said beam.

2. A hay press comprising a Jfeeding chamber, a plunger therein, aplunger rod connected With the plunger, a support, a Crank memberconnected with the support, means for connecting one end of the crankmember With the plunger rod, an upwardly extending part on the crankmember, a rotatable cross head carried by the support and having a pairof projections therein for engaging the upwardly extending part of thecrank member and means for rotating vsaid cross head.

In testimony whereof l aliix my signature.

RALPH M. HILTON.
